W1353, Section 19, Nangung-Panjang junction, Karnali (Permian of Nepal)

Where: Nepal (29.5° N, 83.1° E: paleocoordinates 52.6° S, 61.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Nangung Formation (Namlang Group), Wuchiapingian (259.9 - 254.2 Ma)

• Nangung Formation is correlated with the Kalabagh Member of the Salt Range based on brachiopods, which is Wuchiapingian in age. 30 m thick.

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified sandstone and lithified shale

• Mainly quartzite, some shale.

Size class: macrofossils

Preservation: cast, original calcite

Collection methods: bulk,

• Some collections were of individual specimens, others as large as possible under the circumstances, with a few localities represented by rock weighing more than 50 kg. Most collections were made from just over 50 measured sections, and are under good stratigraphic control.
